I personally might have cropped out some of the bottom (to their waists) and some of the hedge on the right to bring the focus a little more on the children's upper bodies, but however you crop it, it's a great photo for "sound." 8
*wince* Ack. Kids screeching. Yes, yes, very obvious connection to the topic. Very candid snapshot style, not my favorite subject in general but I have no technical complaints.
First thought, sign language hush request. If that's the point, the challenge is met. It seems a bit snapshotty, I'm unsure if the blur (motion?) of the hands adds or detracts. Would rate at 6 if I was voting.
Oh, yes...I can relate. Those kind of beings CAN make a lot of noise. I like the action of the hands. Nice family snapshot and looks as if they had a lot of fun posing for it. I think it would have portrayed noise just a little better if the kids would of had their faces more toward the camera to see their expressions.
